. To all whom it may concern."

Be it known that I, RICHARD VON FOREG- GER, a subject of the Emperor of Austria- Ilungary, residing at New York city, in the county of Richmond and State of New York, have invented a certain new and useful Improvement in Apparatus for Regenerating Air, of which the following is a specification.

This invention relates to an apparatus for the regeneration of vitiated air wherein the aisle caused to pass over a suitable com pound adapted to generate oxygen and absorb carbon dioxid by reaction with said air.

bodiment of the invention the features there- -of being more particularly set. forth hereinafter in the claims.

Figure 1 is aside elevation of the apparatus partly in longitudinal section alongthe line AB of Fig. 2 and showing the arts in engaged position so that the cage is a apted to turn; Fig. 2 is a plan view of the same the upper half of the housing being removed and certain arts disengaged to permit the removal of t 1e cage; Fig. 3 is a front elevation of the apparatus parts being omitted; Fig. 4 is a cross sectional view' along the line OD of Fig. 1; Fig. 5 is a rear end view of the cage on a slightly enlarged scale; Fig. 6 is a detail view on an enlarged scale partly in section of the locking and turning means for the cage; and Fi 7 is a front view of the gear for driving t e cage.

Similar numerals indicate similar parts throughout the several views.

1 represents a base or standard su porting the lower part 2 of a housing provi ed with flanges 3-3. The upper part 4 of the housing is provided with flanges 5-5 adapted to cooperate with flanges 33 and to be bolted thereto. One end of the cylindrical receptacle made by the housing is left open and across it is arranged a strap or brace 6 bolted to the lower art 2 of the housing as shown in Fig. 3. T e other end of the housing is adapted to fit over the exhaust of a blower 7 as at 8. The blower 7 is driven by a suitable motor 10 through shaft 9, said shaft 9 carrying on its extreme outer end a pulley 11 adapted to drive a pulle 12 on shaft 13 journaled in the sides of t e lower part 2 of Shaft-13 carries a worm gear 14 adapted to engage a gearwheel 15 turning on the inner end of the exhaust of blower 7. Gear 15 carries pins 16] 6 projecting outwardly. I

17 re resents a cage formed of wire and adapte to co tain the compound to be used to regenerate the air. 17 is provided with a ring 18 having erforations in its periphery through which t e ends 19 of the wires forming the cage are bent and project so as to form an end for the cage and 101d said wires in position. The other end of the cage is formed by bending the ends of One end of the cage the wires at right angles and securing them in a ring 20 provided with a central 0 ening 21. A s ring controlled rod 22 is s idably supporte on strap 6 and takes into the opening 21 in cage 17, the spring being so arranged that it will normally hold the rod in said 0 ening. Said rod may also carry a scraping nife 23'of any suitable description for scraping the paste off the end of the cage.

24 is a scraper fastened to the cage itself which contacts with and scrapes the interior of the housing as the cage turns. The cage is journaled to turn on the end of rod 22 and the end of the exhaust of blower 7 as shown.

25 indicates a door hinged at 26 and adapted to take under a projecting wire 27 on the cage for the purpose of affording access to the interior thereof.

28 is a catch for holding door 25 in position.

29 is a drawer in the base or standard 1 to receive the particles falling from the cage.

30 is a handle for withdrawing the drawer from the standard.

The plpleration of the a paratus is as follows. e cage having been filled with a suitable substance, for example fused sodium peroxid, the apparatus is started by means of motor 10 which drives the blower 7 forcing air through the cage 17 out through the open end of the housing, the blower exhaust formin a clear, uninterru ted passage from the b ower to the cage. otor 10 through shaft 9; pulleys 11 and 12, shaft 13 and worm 14 drives the gear 15 which inturn, because of pins 16 resting between the wires of the cage 17, turns said cage 17 so that the sodium peroxid is agitated or tumbled about. The passage of the air from the blower over the sodium peroxid will free oxygen and cause carbon dioxid to be absorbed forming a carbonate crust which will be caused to drop off the sodium peroxid by reason of the tumbling and will 1' all into the drawer 29 where it will continue to absorb carbon dioxid for a time and may then be removed. The regulation of the generation of oxygen is attained by changing the speed of rotation of the cage or by regulating the removal of the crust of carbonate or bicarbonate from the peroxid.

It is obvious that the humidity of the air may be increased by any desirable means while the air is passing either through the blower or the cage.

I do not restrict myself to the details shown and described as they may be varied without departing from the spirit of my invention.

What I claim is:

1. In an apparatus for the chemical purification of air, a receptacle, means for supporting the same, a blower in communication with said receptacle, a ear wheel rotatable on the exhaust of sai blower, means for driving said gear wheel and means for coupling said gear wheel and said receptacle.

2. In an apparatus for the chemical purification of air, a receptacle, means for rotatably supporting the same, a blower in communication with said receptacle, a gear wheel rotatably su orted on the outside of the exhaust of saii lower, means for driving said gear wheel and means forengaging and disengaging said gear wheel and said receptacle.

3. In an apparatus for the chemical purification of air, a receptacle, a housing therefor, means for supporting said receptacle within said housing, means for rotating said receptacle, a scraper mounted on said rece tacle adapted to scrape the interior of said housing and a blower in communication with said receptacle.

4. In an apparatus for the chemical purification of air, a receptacle, means for su porting the same, means mounted on sair su orting means for scraping said receptacle, a blower in communication with said receptacle, a gear wheel rotatable on the exhaust of said blower, means for driving said gear wheel and means for detachabl coupling said gear wheel and said receptac e.

5. In an apparatus for the chemical purification of air, a receptacle, a housing therefor, means for supporting said receptacle within said housing, a scraper on said supporting means adapted to act on said receptacle, means for rotating said receptacle, a scraper mounted on said receptacle adapted to scrape the interior of said housing and a blower in communication with said receptaclea In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.

RICHARD VON FOREGGER.
